I-calculator yemithetho ye-Ohm

Kuxazululwe i-voltage, umsinga, ukumelana noma amandla — faka noma yikuphi okubini kwezine.

Ixabiso oluluxazulula livela kulezi ezimbili ozingenisa.

A
Ω
W
Faka amandla endaweni ye-V/I/R ukuze uxazulule kusuka kulo.

Iziphetho zivuselelwa uma ubhala.

Malunga nale khadi

the power of a resistor is equal to the current of the resistor, the power of the resistor is equal to the current of the resistor. The power of a resistor is equal to the current of the resistor. The power of a resistor is equal to the current of the resistor. The power of a resistor is equal to the current of the resistor. The power of a resistor is equal to the current of the resistor.

Imibuzo ebuzwa kaningi

Yini umthetho ka-Ohm?

Imithetho ye-Ohm ichaza ukuthi umsinga osuka ku-conductor ulingana ne-voltage ngaphesheya kwayo: V = I × R. Iphinde yamiswa, I = V / R ne-R = V / I.

Ngiyithola kanjani amandla kagesi kusuka kumthetho kaOhm?

Umandla yisikhathi se-voltage isikhathi esikhona, P = V × I. Ukusebenzisa umthetho ka-Ohm ungabhala futhi njenge-P = I² × R noma i-P = V² / R — zonke ezintathu zinikeza ama-watts afanayo.

Yini amaxabiso amabili engifaka?

Khetha inani elilahlekile ku "Solution for", bese ufaka noma yiziphi ezimbili ezikhona. Ukuthola ukumelana unganikeza i-voltage ne-current, noma amandla ne-current.

Ingabe ngisebenzisa amandla endaweni ye-voltage noma i-current njenge-input?

Yebo. Indawo yokusebenza ethuthukisiwe ikuvumela ukuthi uxazulule kusuka kumandla ongeziwe okunye ubukhulu — isibonelo, 24 W kufaka ku-2 A ibuyisela 12 V no-6 Ω, usebenzisa i-V = P / I ne-R = P / I².

Ingabe umthetho kaOhm usebenza kuma-circuits we-AC?

Isebenza ngokuqondile kungxenye emelana ne-AC circuit. Isebenzisa ama-circuits ane-capacitors noma ama-inducers ushintsha ukumelana no-impedance, futhi amandla athatha i-power factor, kodwa i-resistor elula ilandela i-V = I × R ngaso sonke isikhathi.

Kungani i-resistor yami ithola ukushisa - inamandla angakanani akhipha?

Umncintiswano ushintsha amandla kagesi abe ukushisa ku P = I² × R watts. Umncintiswano we-6 Ω ophethe i-2 A ususa 4 × 6 = 24 W, ngakho-ke udinga amandla aphezulu ngaphezu kwalokho. Ukuncipha kwe-wattage kuyisizathu esijwayelekile sokuqhuma noma ukulahlekelwa umncintiswano.

Ingabe lokhu kuphatha izingxenye ezingaba yi-linear ezifana ne-diodes noma i-LEDs?

Akukho. Ohm umthetho ithatha ukumelana njalo, ngakho ayikho imodeli diode, LEDs noma transistors okungukuthi okwamanje ukhula non-linearly nge voltage. Uhlelo LED ungakwazi endaweni ubukhulu isigaba resistor kusuka ukuhlinzeka voltage kunciphisa LED ukuqhubeka voltage.
